METHODS: Thereby, different functionalities such as sorting, filtering and finding similar cases are included. To provide an appropriate layout and arrangement of 3D models that optimally supports working with the database, three layouts (flat, curved and spherical) and two distances are evaluated. A broad audience study with 61 participants was conducted to compare the different layouts based on their ease of interaction, to get an overview and to explore single cases. Medical experts additionally evaluated medical use cases.
RESULTS: The study revealed that the flat layout with small distance is significantly faster in providing an overview. Applying the virtual data shelf to the medical use case intracranial aneurysms, qualitative expert feedback with two neuroradiologists and two neurosurgeons was gathered. Most of the surgeons preferred the curved and spherical layouts.
CONCLUSIONS: Our tool combines benefits of two data management metaphors, resulting in an efficient way to work with a large database of 3D models in VR. The evaluation gives insight into benefits of layouts as well as possible use cases in medical research.
方法:因此,不同的功能,如排序,包括过滤和查找类似病例。为了提供3D模型的适当布局和布置,以最佳地支持使用数据库,三种布局(平面,弯曲和球形)和两个距离进行评估。对61名参与者进行了广泛的受众研究,以根据他们的互动便利性比较不同的布局,以获得概述并探索单个案例。医学专家还评估了医疗用例。
结果:研究表明,距离较小的平面布局在提供概述方面明显更快。将虚拟数据架应用于颅内动脉瘤的医疗用例,收集了两名神经放射科医生和两名神经外科医生的定性专家反馈。大多数外科医生更喜欢弯曲和球形布局。
结论:我们的工具结合了两个数据管理隐喻的好处,从而在VR中使用大型3D模型数据库的有效方法。该评估可深入了解布局的好处以及医学研究中可能的用例。
